DETAILED DESCRIPTION

Turning to FIG. 1, the disclosed embodiments provide a security system (system) 100 that enables wireless communicating two-way (bidirectional) voice, by a network 110, which may be a short range network such as a local area network (such as WiFi) or a personal area network (such as Bluetooth). The system 100 may include a hub station 112 having a hub station housing 113, a control panel 114 for the hub station 112 with a hub station electronic controller 115 therein (illustrated schematically). A plurality of client stations 120 are provided, for example four such client stations 120 a-120 d are identified in FIG. 1. Such client stations 120 are provided throughout an installation area 130. Each of the client stations 120 includes within one of a plurality of client station housings 121, one of a plurality of client station speakers 122, one of a plurality of client station microphones 124, one of a plurality of client station transformers 126 (illustrated schematically) and one of a plurality of client station controllers 127 (illustrated schematically).

The system 100 provides communications (bidirectional) between the system 100 and a central station 150, via a central station controller 151 (illustrated schematically), that is remotely located over a further network 145 which may be a long range network such as a wide area network distributed over the Public Switched Telephone Networks (PTSN). The client stations 120 may be distributed throughout architectural zones (zones) 140, including for example four distributed zones 140 a-140 d of the installation area 130, that are in addition to a primary zone at the hub station 112. The installation area 130 maybe a private residence and the zones 140 may be separate rooms and/or on multiple levels therein.

There are typically packaging limitations at a hub station 112. By packaging the client station speakers 122 and client station microphones 124 with the client station transformers 126 at the client station housings 121, such limitations are avoided. Instead larger and more powerful speakers and microphones for the client station speakers 122 and the client station microphones 124 may be utilized. This configuration may provide a larger communication range at the client stations 120. In some embodiments the client stations 120 may include video displays 128 and may be capable of video capture.

The system 100 provides a relatively enhanced communication range. The client stations 120 are configured to annunciate programmable status messages, such as “front door open”, throughout the installation area 130. The status messages provide an understanding of a state of the security system to a system user 160, whom may be a homeowner.

FIG. 2 is a flowchart illustrating a method of monitoring for an alarm condition with the client stations 120. As illustrated in box 510 the method includes communicating, bidirectionally, with the hub station 112. As illustrated in box 520 the method includes communicating, bidirectionally, with the central station 150 through the hub station 112.

FIG. 3 is a flowchart illustrated further aspects of the method of FIG. 2 more specifically of communicating, bidirectionally, with the central station 150 through the hub station 112. As illustrated in box 550 the method includes transmitting to the central station 150 through the hub station 112 first data representing first sounds received from a client station microphones 124. As illustrated in box 560 the method includes transmitting from the client station speakers 122 second sounds obtained from second data received from the central station 150 through the hub station 112. As illustrated in box 570 the method includes transmitting from a client station display first images obtained from third data received from the central station 150 through the hub station 112. As illustrated in box 570 the method includes transmitting to the central station 150 through the hub station 112 fourth data representing images received from a client image sensor of the client stations 120.

With the above disclosed embodiments, a hub station 112 may communicate with an array of client stations 120. This configuration may enable voice, and for example video, communications from multiple zones 140 within an installation area 130. This provides capabilities such as being able to triangulate sound source location within or proximate one of the zones 140. During an emergency, such a location could be provided to medical services 170 and other first responders via the central station 150.

Turning to FIG. 4, the disclosed embodiments pool communications for a group 200 of two or more of the plurality of the client stations 120 during an alarm condition. The group 200 can be collectively assessed by the control panel 114, for example as one collective audio/video channel. In the illustrated embodiment the group 200 includes a first client station 120 a and a second client station 120 b of the plurality of client stations 120, respectively located in a first zone 140 a and a second zone 140 b of the plurality of zones 140. In the illustration, these zones 140 a, 140 b are located on a common level 180 of the installation area 130. The common level 180 may be a level in which a particular person 190, such as an infirmed person, spends their time and where such person would need to be addressed during and alarm condition.

Additionally, according to an embodiment, external communication routes 210 may be communicatively connected to the group 200 by the system 100 through the network 145 by action of the control panel 114. Such sources may be provided with networked two-way audio and video capabilities. For example, if the system detects that a personal panic alarm has sounded in one zone, electronic contact addresses, which may be phone numbers, stored in the system 100 for example at the control panel 114, may be automatically contacted by the control panel 114 and bridged into the network 110 to the client stations 120 in the group 200. Applications of the disclosed embodiments includes automatically bridging a doctor 220 via the external communication routes 210, or in addition or as an alternative, members of a family whom are remotely located. In addition, medical services 170 may be bridged to the grouped stations. That is, in addition to be summoned by the central station 150, medical services 170 may be connected over the network 145 for direct two way communications with the client stations 120 in the group 200. Two way voice, and in one embodiment video, communications may be enabled by the system with the connected family members and emergency service personnel. In addition, such two way communications may include personnel at the central station 150 so required efforts are coordinated.

As illustrated in box 660 the method includes establishing another bidirectional communication upon establishing the first bidirectional communication and the second bidirectional communications.

Benefits of the disclosed embodiments include coalescing audio and/or video access points at the client stations 120 of the group 200 enables enhanced coverage for two-way communications with a central station 150. According to the disclosed embodiments, the control panel 114 may store contact addresses for the external communication routes 210 to be automatically connected to the client stations 120 that are in the group 200. Thus, desired persons and resources may be automatically contacted in the event of an emergency.

Turning to FIG. 6, the disclosed embodiments provide for storing information about the different zones 140 for the plurality of client stations 120 to assess various audio signal characteristics. The disclosed embodiments enable determining where in the installation area 130 an alarm condition, such as a sound source by action of an intruder 250, is being detected. For example, an initial alarm condition may be detecting an intrusion at a door-window sensor, for example in one of the zones 140 proximate a level 260 that is associated with a garage. Thereafter, the system 100 may monitor for movement of the intruder 250 by monitoring audio signals at each of the plurality of client stations 120. Through monitoring of audio characteristics such as changing frequency and amplitude of sounds at or proximate the plurality of client stations 120, the system 100 may determine that a source of a dominant sound, such as the intruder 250, is moving between client stations 120 and therefore moving between zones 140 in the installation area 130.

Benefits of the disclosed embodiments include enabling the central station 150 to track a developing alarm condition in an installation area 130 and relay such information, for example to law enforcement agencies 300 over the network 145. The same information may be utilized to identify location of medical distress within one of the zones 140 in the installation area 130, thereby enabling the central station 150 to communicate with medical services 170 and identify a specific location of a need within the installation area 130.

This process allows for a better understanding of nuances of sound propagation and sound characteristics in and around each of the zones 140 of the installation area 130. The calibration process may occur, for example, manually and periodically when the system is activated. During calibration, each of the plurality of client stations 120, one after another, may emit one of a plurality of a test tones 350, including for example four sets of test tones 350 a-350 d respectively from the plurality of client stations 120. The hub station 112 may also emit one of the test tones 350. Though this calibration process, the control panel 114 may develop a tonal map for the installation area 130 and within for each of the zones 140, which may later be used to identify a souse of an alert condition (as indicated above). In addition, through the calibration process, a performance of the system is optimized.
